BOSTON — The two best power threats on the Red Sox are in a simultaneous slump.

Mike Napoli may get a day off on Sunday, to effectively rest him for two days with Monday's off-day. The Red Sox first baseman is 4-for-19 on the homestand, although he still leads the majors with 23 extra-base hits and an MLB-best 16 doubles.

"Quite a bit of thought and even to the point of conversation after last night's game," Sox manager John Farrell said of Napoli. "Mike has shown to get into some really strong streaks and there's been other times where we've got to ride that with him. And I think what he's going through is not something new to him. And yet with tomorrow being another day game and Monday being the off-day, we're trying to find ways to get back-to-back days off. And that may take into account the first day in Tampa (on Tuesday) as well. We're in a pretty good stretch — after Monday's off-day, June 3 I think is the next one. We've got to balance some things out here going forward."

David Ortiz is in an 0-for-16 slump, although he's still got great numbers himself, including a .338/.377/.634 line. Asked if Ortiz had been affected by the controversy surrounding him and questions of steroid use, Farrell said that was not the case: "I can’t say the story has affected him in the result of what the last three days have been."
